go to nissan pick up the o-ring for the sending unit in the tank cause the old one will swell and wont line up once you pull the sending unit out to test it.
under the carpet in the hatch area is an access panel for the fuel sending unit. detach it and lift it out of the way. the harness runs through this plate so you will need to unplug it to move it far enough. once its out of the way and you have the plug disconnected. go start the car run it till it dies. crank it a few more times. now your fuel pressure is released.
unbolt the sending unit by the 6 8mm bolts. lift the unit out carfully. it will be nessesary to fish it around a bit so the float will come out freely. once out reconnect the electrical connector.
now go turn the ignition to the on postion so the gauge registers. hold the unit up and allow the float to fall all the way to the bottom while holding it there look at your fuel gauge should read empty and if you have a low fuel level light it should be on.
next lift the float to the top and look at your dash should read full. then if both those checks are ok,very very slowly lower the float while watching your gauge . the gauge compensates for fuel slosh so it will not fluctuate as fast as you move your float so your speed of travel has to be extreamly slow so as not to pass the glitches.
If you have an ohm meter it is easier to find the glitches. you just prob the connector one the 2 pins for the float sensor.
